1-Form-A Solid State Relay with
Integrated Current Limit
Description
The CPC1510 is a 1-Form-A normally open Solid
State Relay with an integrated current limit feature
that can replace electromechanical relays while
enhancing the robustness of wireline-interface
applications.
The relay is constructed using a GaAIAs LED for
actuation control and an integrated monolithic
die for the switch output. The die, fabricated in a
high-voltage dielectrically isolated technology, is
comprised of a photodiode array, switch control
with active current limiting circuitry, and MOSFET
switches. The active current limit circuitry in the
CPC1510 also provides a thermal shutdown feature
offering excellent power cross immunity for improved
survivability in harsh environments.
These enhancements greatly improves the
robustness of end systems using this device
compared to systems using relays without the
integrated current limit. In addition, the active
current limit circuitry enables the CPC1510 to pass
FCC 68.302 and other regulatory voltage surge
requirements when adequate overvoltage protection
is provided. The CPC1510 relay may be used
in both unidirectional DC applications as well as
bi-directional AC applications.
